INTRODUCTIONInjecting drug abusers are vulnerable to many infectious complications. We describe a case of tetanus in a Singaporean who regularly abused buprenorphine.
CLINICAL PICTUREA 49-year-old male was hospitalised for progressive generalised spasms associated with dysarthria and opisthotonus. Tetanus was diagnosed clinically.
TREATMENTSupportive management was instituted in the intensive care unit (ICU). Toxicology samples tested positive for buprenorphine.
OUTCOMEHe recovered rapidly and was transferred out of the ICU after 8 days. Retrospective questioning confirmed parenteral abuse of buprenorphine.
CONCLUSIONThis case highlights an uncommon and potentially lethal complication of parenteral drug abuse.

A 46-year-old man presented with a six-month history of lumps in the sole of his left foot. Physical examination revealed two nodules, one tender and one firm, at the plantar left foot with no overlying skin changes. Although the initial radiographs were normal, magnetic resonance imaging of the left foot demonstrated two nodules along the medial band of the plantar fascia, characteristic of plantar fibromas. The patient opted for surgical excision. There was no further recurrence of symptoms after surgery. We describe the clinical and radiological features of plantar fibromatosis and briefly discuss other causes of lumps and pain in the sole of the foot.
